This is because you are using same 'name' attribute which means that u can select any one value but in the above code you have given value as true for both the radio button so make any of the radio button value as false as per your requiremnt.
<div class="radio">
<label>
<input name="cycle" type="radio" class="ace" id="Cprocess" value="True" />
<span class="lbl"> Cycle In Process</span>
</label>
</div>
<div class="radio">
<label>
<input name="cycle" type="radio" class="ace" value="False" id="CstartEnd"/>
<span class="lbl">Cycle Start And End</span>
</label>
</div>
